GLA'RE-IREVENTING ATTACHMENT non. HEADLIGHTS. J

Application fired June 3, 1925. Serial No. 34,549.

To all whom it may concern: Be it known that I, JoniN R. PERFATER, a citizen of the United States, residing at Hampton, in the county of Elizabeth City and State of Virginia, hav invented certain new and useful Improvements in Glare-Preventing Attachments for Headlights, of which the following is a specification.

This invention relates to glare preventing attachments for headlights, and the primary object thereof is to provide an' improved type of attachment which can be easily and quickly fitted or applied to the headlight by the purchaser, and which is positively held in position against lateral or other shifting movements. 7

In the drawlngs Fig. 1 is a front elevation, partly broken away and in section, showing the invention applied to a headlight;

Fig. 2 1s a sectlon on line 2-'2 of Flg. 1; and

Fig. 3 is aside elevation of the invention detached from the headlight,

In proceeding'in accordance with the pres ent invention, a translucent glarepreventing member 1, preferably of colored celluloid, is employed. The member 1 is of segmental shape and is provided at its inner end with an opening 2 to receive the usual socket 3 of the electric lamp L. The surface of the I member is shaped to generally conform to that of the parabolic reflector 4-. The outer end of the member is formed with a series of spaced cuts, forming a corresponding series The member 15 originally V of fingers 5. formed of a length in excess of the requirements, so that any variations in the radii of the reflector, can be compensated for.

In certain types of headlights, packing, in the form of cord 6, is employed to cushion the front lens, the present invention being designed for use with such types.

In order to apply the attachment,-the eleo tric lamp is removed, the modifier applied and the lamp then replaced. The modifier is forced into firm surface contact with the parabolic reflector in which position 'the fingers 5 will overhang the front edge of the reflector. The front edge of the reflector is now used as a form and the fingers 5 are bent downwardly thereabout. If the fingers are too long same may be easily cut with scissors. The cord is now sufiiciently disengaged from its holding groove to permit preferably the endmost fingers 5 to be disposed to the rear of the cord, the remaining fingers being disposed to the front of the cord. The front lens F is then repositioned, and the latter firmly forces the cord against the endmost fingers 5, and into'the packing groove 8,automatically conforming or shaping sameto agree with the cross-sectional curvature of the groove. Thus the light modifier is firmly held in position, the fingers being engaged on opposite sides of the cord andbeing clamped between the latter and the lens and the reflector front edge. Due to the spacing of the'fingers, same further are clamped in position, at'a plurality of points. The curvature imparted to the endmost fingers 5' causes same to be interlocked in the packing groove, or to be virtually hookedinto engagement with the groove and,

packing, effecting positive and fixed securement of the member 1 holding same firmly against movement. I

What is claimed is:

1. In combination with a headlight and the'cord packing thereof, a glare preventing attachment composed of a substantially segmental body having an opening at its inner end to receive the headlight lamp socket, and having a series of spaced fingers at its outer end, the endmost fingers being engaged on the rear of the packing and the remaining fingers on the front of the packing, said fingers being formed of yieldable materialwhereby upon engagement of the headlight lens with the fingers and packing the latter will force the endmost fingers into the packing groove and conform same in shape thereto.

2. In combination with a headlight and the cord packing thereof, a glare preventing attachment composed of a substantially segmental body having an opening at its inner end to receive the headlight lamp socket, and having a series of spaced fingers at'its outer end, some of the fingers being engaged on the rear of the packing and others on the front thereof, the fingers being yieldable whereby upon engagement of the headlight lens with the packing the latter .will force the fingers on the rear of the packing into In testimony whereof I affix my signature.
